7. Telco Ltd is manufacturing files and folders from the old clothes to discourage useof plastic files and folders. For this, they employ people from nearby villages where very less job opportunities are available. An employee, Harish, designed a plan for the cost reduction but it was not welcomed by the production manager. Another employee gave some suggestion for improvement in design, but it was also not appreciated by the production manager.

• State the principle of management described in the above para.
• Identify any two values that the company wants to communicate to the society.(Compartment 2014)

8. Voltech India Lid is manufacturing LED bulbs to save electricity and running under heavy losses. To revive from the losses, the management thought of shifting the unit to a backward area where labour is available at a low cost. The management also asked the workers to work overtime without any additional payment and promised to increase the wages of the workers after achieving its mission. Within a short period the company started earning profits because both the management and the workers honoured their commitments.(Compartment 2014)

Question 10

A 20-pole alternator is having 180 identical stator slots with 6 conductors in each slot. All the coils of a phase are in series. If the coils are connected to realize single-phase winding, the generated voltage is V1. If the coils are reconnected to realize three-phase star -connected winding, the generated phase voltage is V2. Assuming full pitch, single-layer winding, the ratio V1/ V2is, A three-phase slip-ring induction motor, provided with a commutator winding, is shown in the figure. The motor rotates in clockwise direction when the rotor windings are closed?

Question 11

In a constant V/f control of induction motor, the ratio V/f is maintained constant from 0 to base frequency, where V is the voltage applied to the motor at fundamental frequency f. Which of the following statements relating to low frequency operation of the motor is TRUE, A three-phase, 4-pole, self excited induction generator is feeding power to a load at a frequency f1. If the load is partially removed, the frequency becomes f2. If the speed of the generator is maintained at 1500 rpm in both the cases, then?

Question 12

A three phase synchronous generator is to be connected to the infinite bus. The lamps are connect ed as shown i n t he fi gur e for t he synchronization. The phase sequence of bus voltage is R- Y- B and that of incoming generator voltage is R' - Y' - B'. A 3 phase, 50 Hz, six pole induction motor has a rotor resistance of 0.1 and reactance of 0.92 . Neglect the voltage drop in stator and assume that the rotor resistance is constant. Given that the full load slip is 3%, the ratio of maximum torque to full load torque is?

Question 13

For a specified input voltage and frequency, if the equivalent radius of the core of a transformer is reduced by half, the factor by which the number of turns in the primary should change to maintain the same no load current is, A three-winding transformer is connected to an AC voltage source as shown in the figure. The number of turns are as follows : N1= 100, N2= 50. If the magnetizing current is neglected, and the currents in two windings areI2= 2 30 A andI3= 2 150 A, then what is the value of the currentI1in Ampere?

A 4-pole, separately excited, wave wound DC machine with negligible armature resistance is rated for 230 V and 5 kW at a speed of 1200 rpm. If the same armature coils are reconnected to forms a lap winding, what is the rated voltage (in volt s) and power (in kW) respectively at 1200 rpm of the reconnected machine if the field circuit is left unchanged , The synchronous generator shown in the figure is supplying active power to an infinite bus via two short, lossless transmission lines, and is initially in steady state. The mechanical power input to the generator and the voltage magnitude E are constant. If one line is tripped at time t1by opening the circuit breakers at the two ends (although there is no fault), then it is seen that the generator undergoes a stable transient. Which one of the following waveforms of the rotor angle shows the transient correctly?r
